MATLAB: Histogram with counting number of “1” per bin

histogram

Hi,
I have the following data: The intensity of a stimulus can be varied on a certain range, subjects have to say then for each intensity, if they can perceive the stimulus. Out of this data I would like to plot a histogram – and so far I have not found any existent Matlab function to do so (?).
So say the data would look like:
A = [100 120 80 85 130 145 160 95 105 110 115 135 150;
      0   1   0  0   1  1   1   1  1   1   0   0   1]
and I would like to split up the range [80,160] into 4 bins and count the number of 1's for each bin.

Try this:
A = [100 120 80 85 130 145 160 95 105 110 115 135 150];
counts = [ 0   1   0  0   1  1   1   1  1   1   0   0   1]
edges = linspace(80, 160, 5) % % 5 edges for 4 bins
myHistCounts = histcounts(A.*counts, edges)
works as long as your counts are only 0 and 1. You can have two of the same value, like 2 at 120 with a 1 as long as the 120's are separate, which I think they would be because each element is for one stimulus.
